Application filed May 29,1905- Serial No. 262,766.

To all whmn it may concern.-

Be it known that I, JAooB SOHAEFFER, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Hydraulic Motors; and Ido herebydeclare the following to be a full, clear, and exactdescription of the invention, such as will enable others, as well asthose skilled in the art to which it appertains, to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis s ecification.

My invention relates to fiydraulic motors,-or that class of deviceswhich is operated by means of the utilization or manipulation of Wateras a motive power ;-and are so constructed as to be able to transmitsaid power in such a manner as to run or operate any small device ormachine,but more especially washing machines,for which purose myimproved motor is more especially designed and intended.

Some of the principal objects or purposes,and advantages of myinvention;- consist in producing a water motor as above referred to, ofsimple construction; composed of few parts; inexpensive in cost ofmanufacture, and one which will work automatically and give more perfectresults than heretofore obtained from other devices of a similar nature.

The invention consists of the very peculiar and novel arrangement,construction and combination of the various mechanical parts, as will bemore fully referred to in detail hereinafter, and set forth in thesubjoined claims in accordance with the statutes in such cases made andprovided therefor.

In the annexed drawings constituting a formal part of thisspecification, and wherein the same letters of reference indicate thesame parts wherever occurring throughout the several views :Figure 1, isa plan view of my hydraulic motor. 'Fig. 2, is an inverted plan viewpartially in section, of one of the movable valve-rods and its springcatch, and the boX or case inclosing same. Fig. 3, is an inverted planview of the hookedend of one of the movable valve-rods, and its sring-catch. Fig. 4, is a side elevation of t e motor. Fig. 5, is a sideview partially in section of the two-way valve and stuffing boX. Fig. 6,is an end elevation of the motor. Fig. 7, is a broken away longitudinalsectional view of a portion of the cylinders; the head to saidcylinders; and the two-way valve. Fig. 8, is a plan view of the movablevalve rods, the flat spring for actuating them, and the inclosingcasing; and Fig. 9, is a perspective view of a broken away portion ofthe vertical shaft, with the disk, short sleeve and sprocket-wheel heldin position thereon by the retaining-pin.

In describing my said invention specifically, and referring in detail tothe different parts or various mechanical elements or features ofconstruction, which combined, make up my improved hydraulic motor, asshown throughout the various views of the drawings and indicated bymeans of the letters of reference as aforesaid, a, designates the twowayvalve provided with the usual stufiingboX and retained in position inthe forward cylinder head by an ordinary nut Z through which valve-stem0 passes :said valve being shown in a position turned sufficiently so asto allow the water as forced from the city water main,or other suitablesource of supply having suflicient pressure and conducted by means of apipe or rubberhose connected to mouth-piece d see dotted lines in Fig.l;said water passing therethrough, and thence through the concavity orrecess a formed in said valve, and along the channel or water way in theforward cylinderhead'see more particularly Fig. 7, also Figs. 1 and5;into the cylinder C; when said water will strike the plunger orpistonhead f, forcing and moving it and its rodf backward and in thedirection indicated by the arrows, until said cylinder has been filledby the water; and as said piston-rod thus moves backward it will carrywith it sprocket-chain g, which is suitably hooked or detachablyconnected to the end of said piston-rod at h; and said chain thus movingwill turn or rotate sprocket-wheel "i,see dotted lines Fig. 1, alsoFigs. 4 and 9;and with it the clothes-rubber or rubber-head K upon shaftKupo n which said sprocketwheeli also is mounted by means of its shortsleeve i and pin 11 as clearly shown in Figs. 4 and 9 ;it of coursebeing obvious that in practice said rubber-head or its equivalent willrest in the washing-machine of any ordinary construction, whilst theentire motor is intended to be firmly and suitably supported on thewashing-machine by means of base I: which is to be bolted or otherwisesuitably connected thereto in any well known manner: said base beingprovided with a long sleeve i extending up to short sleeve 01 ofsprocket-wheel i, and through which said vertical shaft passes and isheld therein by means of retaining-pin i -passing through said shortsleeve and vertical shaft-see Figs. 4 and 9. Secured at 9' to base I,are the flanges J which form the forward and rear ends or heads of thecylinders G and D, and.

hold said cylinders securely between the same by means of long-bolts 3'in an ordinary and well known manner, as shown: the rear flange J beingformed with collars 9' through which the piston-rods move or play, andthus forming a support or bearing for same.

Firmly mounted upon valve-stem c is a cross-head k, to which is movablypivoted by means of their slotted ends I and Z the valve rods L and Lsaid rods being slightly flattened and having a smooth surface wherethey cross and come in contact, and are provided with shoulders m,asclearly shown in Figs. 1, 2 and 8; whilst the opposite and rear end ofsaid arms rest in a casing or boxing N, and have connected to thempreferably by screw-threads, the hooked ends at and n, which as shownmore particularly in detail in Figs. 2 and 3 are provided with springcatches 0 and 0 so formed at p and p as to be adapted to engage thesides of the boxing or casing, when said, movable rods are forced backto the rear as their springs g and q ,which are held between boxing Nand the annular flanges or washers r and r on said movable rods,arecompressed; as shown by spring g in Fig. 1, and will be more fullydescribed hereinafter.

Now as just above described,the water passing into cylinder 0 will forcepiston-head f and piston-rod f 2 backward, thus causing sprocket-chain gto rotate sprocket-wheel 'L, and thus turn vertical-shaft K, andclothesrubber or rubber-head K also disk S which is formed integral withshort sleeve 11 the same as sprocket-wheel t'see Fig. 9and is located attop of said vertical shaft, which will move in the direction indicatedby the arrows,and which is provided with a small lug or in t,-whichengages the hooked ends of sai movable valve-rods, each in their order;said disk being further provided with fingers a; and as the disk turns,the small lug or pin 25 will move out of its engagement with hooked end11, thus releasing it, whilst finger u will be brou ht to bear againstend p of spring catch 0 forcing said spring catch out of engagement withthe boxing or casing N, which will now permit or allow spring g to reactand expand, throwing movable valve-rod L forward, when its slotted end lwhich is movably connected to cross-head 7c'wi1l move said cross-head,thus turning or reciprocating the two-way valve a in the directionindicated by the arrows,and traveling back in the path it has just come,

but in an opposite direction from the position shown,see Fig. 7-(saidvalve always making a one quarter turn from mouth-piece d to onecylinder; and then reciprocating back again until it passes saidmouth-piece, and makes another one quarter turn to the oppositecylinder;)the rods Lthus causing said valve to continue and complete theturn or reciprocal'movement, until recess e of said valve establishescommunication with the opposite cylinder D ,which now in its turn fillswith water: whilst straight edge 12 of valve (1 has now openedcommunication from cylinder C to the exhaust-port w. Now whilst valve ais in the position shown, and whilst cylinder 0 is filling with water asfirst above described, and the disk, sprocket chain, and wheel, and theshaft are being operated by reason of piston-head f and its rod f 2being forced backward,as indicated by the arrows; through the pressureexerted by the water as it rushes into said cylinder; and as chain 9 hasits opposite end hooked at k to piston-rod 8 it will now move saidpiston-rod and its piston-head 8 forward, until all the water has beenforced out of the cylinder D, and along the channel or waterway of thecylinder-head, and straight edge 12 of valve a,see Figs. 5 and 7,throughexhaust port to and out of waste pi e W.

In some cases it may be found a visable to use a flat spring foractuating the movable valve-arms, as shown in Fig. 8; instead of thecoil springs shown in Figs. 1 and 4; or if a very heavy tension isrequired both the coil and flat sprin s may be employed together; or infact any orm or style of member having sufficient resilience may beemployed, although in practice I expect to employ the flat spring 9 Itwill of course be understood that in practice the cylinders will eachhave a suitable vent or air-opening to prevent them from becomingair-bound.

I wish to be clearly and positively understood, as reserving to myselfthe ri ht under the well known and long establishe doctrine of patentlaw, of making any minor changes in the arrangement, combination, orconstruction of the various parts of my device as may from time to timebe suggested, all within the scope and spirit of the invention, andwithout departing from the principles of the same.

Having now fully and clearly described the construction and operation ofmy device what I claim as my invention is 1. In a water-motor, and incombination with the valve provided with a cross head; of the cylinders;the piston-heads and pistonrods, which have a reciprocal movement insaid cylinders; the sprocket-chain and wheel actuated by thepiston-rods; the movable valve rods connected to the cross-head of saidends of said piston-rods for transmitting with the spring-catch, thespring, and. the disk for actuating said valve-rods; all subl stantiallyas described.
